Legal pages, navbar to footer: a document header or a title band, then the terms or the policy as reading type, in one narrow column or with its contents pinned beside it. Three finished pages.
A section is one full-width band: a hero, a pricing table, a footer. A page stacks several of them into a finished screen, from the navbar to the footer. The sections are the parts, the page is one tested way to put them together.
